Embodiment 1

[0020] Embodiment 1 liquid phase connection peptide reaction general method

[0021] Dissolve the carboxyl-terminally exposed compound in anhydrous tetrahydrofuran (THF), add N-hydroxybenzotriazole (HOBt) to the obtained solution, and slowly add N,N-dicyclohexylcarbon dissolved in anhydrous THF under ice-cooling Diimine (DCC), stirred at 0°C for 15 minutes to obtain the reaction solution (I). The carboxy-terminally protected amino acid was also dissolved in anhydrous THF, adjusted to pH 9 with N-methylmorpholine (NMM), then mixed with the reaction solution (I), maintained at pH 9 with N-methylmorpholine, and stirred at room temperature for 10 h. The progress of the reaction was monitored by TLC. After the raw material point disappeared, the reaction mixture was filtered, and the filtrate was concentrated under reduced pressure to obtain a viscous substance, which was dissolved in ethyl acetate or dichloromethane, and the obtained solution was sequentially washed with 5% NaHCO...

Description

technical field [0001] The present invention relates to 20 kinds of 5-(bis(3-(2-hydroxyethyl)-1H-indole-2)methyl)-2-hydroxybenzoyl-AA-OBzl, to their preparation methods, to their Inhibition of tumor cell invasion and metastasis involves their activity in inhibiting tumor weight gain in mice bearing S180 tumors, and their anti-tumor lung metastasis activity and anti-inflammatory activity. The compound of the invention has good application prospects in the preparation of anti-tumor drugs, anti-tumor metastasis drugs and anti-inflammatory drugs. The invention belongs to the field of biomedicine. Background technique [0002] Malignant tumors seriously threaten human life and health. Lung cancer is one of the most aggressive human cancers. For patients with advanced lung cancer, usually 10%-15% of them can only survive for 5 years. This difficult situation has not improved significantly over the past 30 years. In many clinical cases, lung cancer has metastasized to surround...
